Huh.


Maybe we should saw all of them in half, just to settle the issue. I don't think they are double walled either, but they do have some type interior coating. That's some thick tank walls.

The newer ones are white inside so must be double walled. I've looked at all 4 bikes and have 2 spares. Only the '08 was like this. I really wanted to see how thick the inner white wall was and see if it was "stuck" to the outer wall or just formed inside it somehow.

The tank I cut was folded and bulged for a year after an accident pushed up the sub frame. Never did crack or turn white at the bulge.

Maybe it is semantics. I can't see how you could put an inner tank within an outer one, without some seams showing.

I do see how they could build a tank using the inner one as part of a form to build an outer one around it. But then they would be bonded together and become one.

I have one the first replacement tanks, that was not just old stock. The liner in mine is a very, very dark gray, almost black. It is slick and has a few waves in it. Definitely not the same stuff that shows on the outside.

Add one more!

Purchase a left over 2013 F800GS with a fair rebate, literally I just unloaded the bike from the truck and I notice the cracks on both sides, bike is brand spanking new 3 miles on odometer!!...I guess I'll follow the advise and wait a couple of years just before warranty expires for a replacement and hope for a new design

I'm going to replace it at 600 miles and then again (if needed) right before warranty expires at 3 years.
